chaincode_example02.go:44:2: cannot find package "github.com/pkg/errors" in any of:
/opt/go/src/github.com/pkg/errors (from $GOROOT)
/opt/gopath/src/github.com/pkg/errors (from $GOPATH)
I have included own functions to chaincode example, want to deploy with docker developed mode. But have this error. I am confused where I shoud put the package pkg/errors.
I have made go get github.com/pkg/errors. Still can not find while building chaincode.
